Does anyone know if Van Vlier (with an R) is related to Van Vliet (with a T)? I am descended from Van Vlieren (various spellings: Vleering, Vleerin, Vlierden, Vlierend) of New York State, Ulster or Greene Counties, going back to Colonial days. Van Vlieren (with an R) is relatively rare. Is Van Vlieren its own surname, or related to Van Vlier, or related to Van Vliet, or related to other? It seems VLIEREN is the base name.
